IN BRIEF: Intel Claims Leadership in Supercomputing.

More supercomputers are using Intel Corp.'s chips, according to the latest Top 500 list, Intel said. The high performance computing (HPC) community is especially enthusiastic about the Intel Xeon 5500-series.

The 33rd edition of the TOP500 list shows that 399 of the world's top 500 systems, including two in the top 10, now have Intel inside. Systems using Intel Xeon quad-core processors feature prominently in the list, holding 340 spots. Using reinvented high-k metal gate transistors, Intel's previous-generation quad-core 45nm Intel Xeon processor 5400 series is used in 263 systems.
